In a composite horticultural system, a lower worm culture container contains a worm culture medium for growing worms and converting manure to worm casting type top soil. The top soil is used in a plant growing container mounted above the worm culture container. The environment over the plant growing medium is controlled by an environmental control means comprising a frame with replaceable panels. One set of panels comprises a sheet of translucent material for permitting sun light to pass therethrough and for retaining the heat within the plant growing container, whereas a second set of replacement panels comprises a slat arrangement for shading the plants and for passage therethrough of air for controlling the temperature within the plant growing container. A seed sprouting tray is arranged to be fitted between the bottom of the plant growing container and the worm culture container for using the darkness and warmth between the two media for sprouting of seeds which may then be transferred to the plant growing container. The composite horticultural device is useful as a teaching aid for teaching horticulture and/or as a starter and growing box for horticulture purposes.
